Recent studies found major conflicts between traditional taxonomy and genetic
differentiation of grass snakes and identified previously unknown secondary contact zones …

Using two mitochondrial DNA fragments and 13 microsatellite loci, we examined the
phylogeographic structure and taxonomy of two codistributed snake species (Natrix natrix …

Phylogeography is often used to investigate the effects of glacial cycles on current genetic
structure of various plant and animal species. This approach can also identify the number …

We examined the contact zone of two parapatric species of grass snake (Natrix
astreptophora and Natrix helvetica) in southern France. To this end, we used …

Syria is home to a wide range of ecosystems and landscapes that support a variety of animal
species, including reptiles. Currently, Syria hosts nine species of chelonians (turtles and …

In temperate regions of the Earth Pleistocene, climatic fluctuations significantly influenced
distribution of species. However, little is known on how glacial and interglacial cycles …

The range dynamics of species distributed in temperate zones was significantly influenced
by climatic fluctuations during the Pleistocene. However, little is known on how glacial and …

The herpetofauna of the Indomalayan bioregion of Asia suffers from severe habitat loss,
unsustainable harvesting, and lack of research and conservation. Here, we investigated the …

Under different environmental conditions, hybridization between the same species might
result in different patterns of genetic admixture. Particularly, species pairs with large …

Phylogeographical breaks can be viewed as regional hotspots of diversity where the genetic
integrity of incipient species is put to the test. We focus on an understudied species transition …
